On: Unix history and the `dc` calculator

is your bc the bc or is it a bc? bc is a POSIX standard so "a" bc would be as good as "the" bc, i'm just curious. "man bc" on Fedora linux says the author is Phil Nelson

Depends on what platform you are using. Most Linux distros? Only a bc. FreeBSD and macOS? The bc. [1]
